Adducts of 2'-deoxyadenosine (L) with 3d metal perchlorates were synthesized by refluxing mixtures of ligand and metal salt in triethyl orthoformate-ethanol. Solid complexes of the following types were obtained: (X = C1O4): M2L3X6.4H2O (M = Cr, Fe), M2L3X,.4H2O (M = Mn, Co, Ni, Zn), FeL2X2.2H2O and Cu2L3X4. The Cu(II) complex is magnetically subnormal and appears to be a dimer of the type {O3CIOCuL3CuOCIO3} (CIO4)2 involving a triple bridge of N1,N7-bound L Iigands. The rest of the new complexes exhibit normal ambient temperature magnetic moments and were characterized as linear chainlike polymers comprising a singlebridged (M-L)n backbone, terminal unidentate L, -OC1O3 and aqua Iigands and ionic perchlorate. Bridging L is also Nl,N7-bound in the latter adducts, while the terminal L Iigands present bind most probably via N7. |
